Example Methods

FIG. 1 illustrates an example process for automatically generating video content from scripts/text, according to some embodiments. in step 102, process 100 can receive a textual description of a video. In step 104, process 100 can use text to search a set of relevant assets in a specified video content library. In step 106, process 100 can, based the video content matched to text, determine a location of video content in an output video. In step 108, process 100 can generate and provide video to user that input text. The user can share the video online or via various electronic communications.

In one example, given a text, process 100 can search relevant assets in a local library of video content and/or external libraries of video content. Given a set selected of assets returned from the search, process 100 can then position the video content in a slide/video. It is noted that the output of the video can be of following three formats: digital animation; digital image-based; digital video. Example types of assets in a local library of video content can include, inter alia: backgrounds; characters; properties; music.

Process 100 can implement speech recognition. For example, process 100 can provide a voice-based interface with a speech-to text converter. In this way, process 100 can provide speech-based animation. In one example, based on a time period it took for a user to speak, process 1000 can determine a period to display an associated animation action before the video changes to next slide. This timing can be based on number of characters in sentence if the input is not voice based. The number of characters can be used to set the time to display an associated slide (e.g. as a proxy for how long it takes a user took to speak a sentence, etc.).

Example Systems

FIG. 2 illustrates an example system 200 for automatically generating video content from scripts/text, according to some embodiments. System 200 can implement process 100 and/or other processes provided herein.

System 200 can include an NLP engine 204. Given a text, NLP engine 204 can determine the closest match of assets in a local library of video content and/or external libraries of video content. NLP engine 204 can determine word embeddings. For example, NLP engine 204 can determine use three-hundred-dimension (300-D) word embeddings to convert each word into a vector. NLP engine 204 can use an open-source software library for advanced NLP and an associated model (e.g. en_core_web_lg and the like). NLP engine 204 can implement various sentence embeddings. NLP engine 204 can use determine the final dimensions of each sentence.

NLP engine 204 can use utilize an unsupervised machine-learning algorithm to learn mapping for each asset. For example, a k-means clustering algorithm can be used to cluster text data associated with each asset. NLP engine 204 can learn asset embeddings as a list of embeddings. NLP engine 204 can use can then map each asset to list of vectors (e.g. text converted into sentence embeddings). For each asset, a cluster list of vectors can be set into N clusters (where N is calculated using a silhouette score). NLP engine 204 can use calculate a closest vector to a centroid for all N clusters. These new calculated vectors can be set as the cluster representatives. NLP engine 204 can use list of all cluster representatives together form the embedding for a given asset.

NLP engine 204 can use an algorithm to find the closest asset match, given a text. An example algorithm can include the following steps. NLP engine 204 can use convert the text to vector representation using a specified sentence embedding. NLP engine 204 can use calculate the closest matching assets based on a Cosine Similarity score.

NLP engine 204 can use various datasets. For example, NLP engine 204 can use specified User data. NLP engine 204 can clean this data. In one example embodiments, NLP engine 204 can use utilize experts to manually annotated assets information. NLP engine 204 can implement data cleaning. In one example, NLP engine 204 can considered text which is in English language and ignore text in other languages. NLP engine 204 can considered tokens with various POS (part-of-speech) tags, such, inter alia: i. Noun: NNP, NN, NNS, NNPS ii. Verb: VB, VBZ, VBD, VBN, VBG iii. Adjective: JJ, JJR, JJS iv. Interjection: INTJ v. Adverb: ADV vi. Pronoun: PRON.

System 200 can use large datasets. For example, process 200 can use a text to video method that is not based on a rule-based approach. It rather uses a large amount of human-created animations to learn two things. First, system 200 can learn what assets to fetch for a given sentence (NLP engine). Second, system 200 can learn how to mutually place the fetched assets.

FIG. 3 illustrates an example NLP engine 204, according to some embodiments. In this example, script parser 302. Script parser 302 can return a text/script broken into slides, along with keywords, phrases, nouns and verbs/actions in the form of a JSON. Background fetcher 304 can return a most relevant background scene based on the keywords and phrases. This can be contextual search based on entire sentence and context of sentence, how have others used these phrases, etc. Asset fetcher 306 can return a most relevant set of characters based on the keywords and phrases along with associated attributes. Local video content library 308 can be a local asset library. Additional, information regarding these modules is provided infra.

Returning to system 200, system 200 can include layout engine 208. Layout engine 208 can manage construction of the whole video (e.g. as a sequence of slides). A slide can include either assets from a local asset library and/or images/videos from external sources. Inputs to layout engine 208 are now discussed. A rich JSON can be received by layout engine 208 from the media engine 206. This can be any graphical element. The JSON can include the following elements, inter alia: the raw script, etc. An array of JSON objects can be provided of which each item represents a slide. The array of JSON objects of the following elements, inter alia: the text of the slide; background from the local asset library; the characters and properties from the local asset library with their associated attributes; a hyperlink to the digital images and/or digital videos; flags; keywords and phrases; etc.

FIG. 4 illustrates an example of layout engine 208, according to some embodiments. Layout engine 208 output can include a project XML. Layout engine 208 can include external images/videos module 402 and local images/videos library module 404. Layout engine 208 can implement the following workflow. Based on the flags, a driver function (e.g. driver function 406) calls external images/videos module 402 and/or local images/videos library module 404 to deal with the creation of slide.

External images/videos module 402 uses the digital images/videos from external APIs. Local images/videos library module 404 uses assets from the local asset library. External images/videos module 402 uses the digital images/videos from external APIs: External images/videos module 402 receives the corresponding JSON containing information required to construct the slide. The related media file is then downloaded.

Based on whether the media file is digital image or a digital video one of the following action is performed. If the media file is an image, layout engine 208 can calculate saliency is over the entire digital image. Based on the saliency the digital image can then be cropped and resized in any specified aspect ratio (e.g. 16:9, etc.). The saliency is calculated again over the resized image to determine the area where text is to be placed. This can be implemented by dividing the whole image into five (5) equal regions and then choosing the region with the least standard deviation.

If the media file is a digital video, layout engine 208 can n-frames over the entire video and then merge it. The saliency is calculated again over the resized digital image to determine the area where text is to be placed. Once the alignment is returned the digital image or digital video is added to the background. The text area is then calculated and a rectangular property object of the same size as that of the text box is then added to XML to provide the highlighter effect. The text and the highlighter is then added to slide XML based on the alignment. The required enter and exit effects can also be added. The final slide JSON is then returned to driver function 406.

Returning to system 200, system 200 can include media engine 206. Media engine 206 can provide a support service that accesses and combines data from user system 202, NLP engine 204 and layout engine 208. Media engine 206 can provide the final output video. Media engine 206 can also be used to access external image/video APIs. Media engine 206 can handle uploads and downloads of media content (e.g. digital images/video, etc.) and/or other files (e.g. video XML, HTML, etc.).

In one embodiment, layout engine 208 is characterized by three important aspects. First, the objects and characters are placed in such a way that it looks logical (e.g. humans stand on the ground, chairs are placed of the ground, clouds are placed in the sky, etc.). Second, layout engine 208 provides that the layout of the scene is aesthetically pleasing (e.g. proper gaps are kept between different assets, the alignment is proper etc.). Third, layout engine 208 provides that the mutual interaction of multiple assets is reasonable. Layout engine 208 can use a machine learning approach, where existing human-made animations are used to teach the layout engine. More specifically, layout engine 208 uses the existing data from a large database of human made animations to create probabilistic grid maps. The probabilistic grid maps capture a likelihood of placing a character and/or an object a particular position in the fetched background. Layout engine 208 can also learn a pairwise probabilistic grid map. Pairwise probabilistic grid map captures the likelihood of putting the next asset given the current assets position on the given background. Once learned, the probabilistic unary and pairwise grid maps are used by the layout engine to place individual assets or assets with respect to each other. Accordingly, layout engine 208 can obtain a large amount of data and have the ability to learn from it to improve the methods.

FIG. 5 illustrates an example media engine 206, according to some embodiments. Front-end interface 502 can communicate with user system 202 (e.g. via text, file-system transfer protocols, electronic mail, etc.). Media engine 206 can include upload and download manager 504. Upload and download manager 504 handles upload and download of media content. Media engine 206 can include public cloud storage resource manager 506. Public cloud storage resource manager 506 can manage uploads/downloads from a public cloud storage resource (e.g. AWS S3 cloud platform, etc.). Media engine 206 can include external image/video API module 508. External image/video API module 508 can obtain media content from external sources.

Media engine 206 can provide various inputs. For example, on press of a submit button on the user system 202, media engine 206 receives the following from the front end. Media engine 206 receives a script. The script can have been entered by the user (e.g. see FIG. 10 infra). Media engine 206 receives flags. A flag can be an asset flag. The asset flag can be set to true for animated videos. A flag can be a media flag. A media flag can be set true for digital videos with external images. A flag can be a video flag. A video flag can be set to true for digital videos with external video files. Media engine 206 can provide outputs. For example, in a response Media engine 206 can return a hyperlink to an HTML player with the corresponding XML.

It is noted that system 200 can add sound based on the script. System 200 can handle context; color; multiple characters in one slide; and interactions between characters and properties.

Additional Processes

FIG. 6 illustrates an example workflow process 600 for implementing example embodiments. In step 602, the media engine receives the script and the flags from the front end. In step 604, the raw script is then sent to the NLP engine for parsing. The NLP engine then returns the parsed script in the form of JSON.

FIG. 7 illustrates an example process 700 of an NLP engine then returns the parsed script in the form of JSON, according to some embodiments. In step 702, the original script is obtained. In step 704, this script is broken down into sentences (e.g. each sentence can represent a slide, etc.). In step 706, the keywords and phrases for every slide are determined. These can be further classified into nouns and verbs/actions). In step 708, process 700 implements flags/flagging operations.

Returning to process 600, in step 606, the JSON is to populate every slide with assets, media objects (e.g. digital images/videos) based on the value of the flags. In step 608, based on the flags one or any combination of the following actions is performed.

FIG. 8 illustrates process 800 for implementing flag-based action, according to some embodiments. In step 802, assets and background are fetched from an NLP engine if asset flag is set true. In step 804, digital images are fetched from external API based on keywords and phrases if media flag is set to true and are uploaded to the S3 bucket. In step 806, digital videos are fetched from the external API if video flag is set true and are uploaded to the S3 bucket.

Returning to process 600, in step 610, the fully populated JSON with all the required media (background, assets, images or videos), flags and the script is then sent to the layout engine for further processing. In step 612, the layout engine then returns a Project XML (e.g. the digital video). In step 614, this XML is then embedded in a HTML and both the HTML and XML are uploaded to an AWS S3 bucket and the final hyperlink is sent to the front-end.

FIG. 9 illustrates another example process 900 for automatically generating video content from scripts/text, according to some embodiments. In step 902, the script and video type preference entered by user is passed to media engine. In step 904, the script, along with the preference, is passed to script parser. In step 906, the script parser returns the script broken into slides, along with keywords, phrases, nouns and verbs/actions in the form of a JSON. In step 908, from this JSON, for every slide, the keywords and phrases are sent to the background fetcher to get the background. In step 910, the background fetcher returns the most relevant background based on the keywords and S3-phrases along with associated attributes. In step 912, from this JSON, for every slide, the keywords and phrases are sent to the asset fetcher to get the characters. In step 914, the asset fetcher returns the most relevant characters based on the keywords and phrases along with associated attributes.

The digital video can be a two-dimensional digital video with animations and digital images in background. The background can also include animations. The digital video constitutes of sequence of slides. Every sentence of script can be represented by one or slides. The user can select a 2D animation option. Every asset in the local video-content library has attributes such as ID, URL, height, width, etc. These are used in the construction of the XML.

Example User Interface

FIG. 10 illustrates an example user interface 1000 for automatically generating video content from scripts/text, according to some embodiments.

Heatmap Method

FIG. 11 illustrates an example process 1100 for automatically generating a video from an input text using a heatmap, according to some embodiments. In step 1102, layout engine receives relevant information in JSON format. This can be used for the construction of the output video. This JSON information contains information, such as, inter alia: background identity, object identity, action of the object, color, text to be used etc.

In step 1104, after extracting these JSON information from the JSON content, process 1100 constructs the desired video. The construction of the video corresponds to creating an XML file in step 1106. The XML has various tags related to slide information, object information, text information, etc. Process 1100 can fill these tags with the information extracted from the EON.

In step 1108, the construction of the video is implemented in a slide wise manner. For example, in a given slide, sequential placement of objects and text is performed. First, placement of a character takes place. Process 1100 can use a heatmap algorithm for this purpose. The heatmap can be generated based on the current store of past user's data. Process 1100 can then implement the placement of the text. Process 1100 can use the relative heatmap approach which is based on the heatmap algorithm. In step 1110, the desired XML is generated. This is then sent to media engine module. It is noted that a probabilistic grid map can be a heatmap.

Additional Processes

FIG. 12 illustrates an example process 1200 for automatically generating video content from scripts/text, according to some embodiments. In step 1202, with a fetcher and asset fetcher, process 1200 learns to determine a background to be used with which user input sentences/words from a large amount of previous user data. For example, for a sentence like ‘we went for a date yesterday’, it is desired to show restaurants or cafe as background. Process 1200 can search by keywords (e.g. ‘date’ or ‘yesterday’, etc.), in such a manner (e.g. contextual search, machine learning, etc.) such that the implicit usage of the input terms are learned by machine-learning methods and used.

In step 1204, process 1200 can analyze each background and based on all the sentences which have been used by each background with each of the users. Process 1200 can semantically encode each of these sentences into vectors (e.g. to semantically encode the meaning in a numeric form). Process 1200 can cluster these sentences using a clustering algorithm. Each cluster then represents a broad theme/setting/semantic where the background can be used. For example, a cluster can contain similar sentences like (e.g. ‘we went for a date yesterday’, ‘the date on Friday was memorable’, ‘I am going on a date tomorrow with Lily’, etc.). Similar sentences are grouped and represented by a single vector. This process is repeated for each animated background and each background then associates with multiple such clusters (each cluster representing a situation where this background is relevant). This is termed as training phase.

In step 1206, process 1200 can implement a test phase. Given a new sentence, process 1200 can compare the new sentence with all the cluster centers. Process 1200 can pick the background with a corresponding cluster center is closest to the given sentence and use it for the animation. In step 1208, process 1200 can implement the asset fetching algorithm.

As noted supra, process 1200 can, optionally, also use a voice-based interface for text. Where given a voice instruction, process 1200 convert it into text (e.g. using a speech to text converter). The text is then used for creating the animation. This can enable creation of animation by users with physical disabilities. The duration of the animation slide (e.g. how much it has to be shown) can be decided based on the time user took to speak. Process 1200 can create an animation in any aspect ratio. It is noted that once a layout is applicable, process 1200 can insert asset, text, shapes or any type of animated graphic element. It is not limited to just text and assets.
